Title: Method for reproducing image from moving image information highly efficiently encoded by mpeg system
Inventor: YAMAGISHI TORU
IPC: H04N19/593
Filed: 1993-03-16
Abstract: PURPOSE:To provide an image reproducing method of moving image information highly efficiently encoded by an MPEG system without generating disturbance in reproduced images even when reproduction from the midst is performed. CONSTITUTION:In the case of reproducing the images from the midst of a bit stream composed of the moving image information highly efficiently encoded by the MPEG system where an image frame for which image data are compressed by applying an intra-frame prediction method and the image frame for which the image data are compressed by applying inter-frame prediction coexist, whether or not a GOP which appears for a first time after the point of time when the reproduction from the midst is started is a closed GOP is discriminated.

Title: Membrane purifying method for surface water with improved recovery rate and operation method of its device
Inventor: URANO KOHEI
IPC: B01D61/20
Filed: 1993-03-15
Abstract: PURPOSE:To improve the water permeable performance of a membrane and also to operate equipment for a long period of time by operating a hollow yarn type filter membrane (UF) module by a method substantially close to the full flow filtration and using a concentration tank to recover supernatant fluid from washing water contg. turbid matter caused by backwash. CONSTITUTION:In normal operation, raw water, such as river water introduced from a sedimentation basin 1 is increased in pressure by a pump 11 to feed it to a UF module 12, where turbid matter is removed to turn the raw water into permeated water by the filtering action of an ultrafiltration membrane. The permeated water is stored in a permeated water storage tank 17 through a permeated water automatic valve 13. Next, after a prescribed time (30min-1 hr) has elapsed, backwash is performed for about 30-60sec. That is, the supply of the raw water is stopped and also a pump 18 is operated to feed the permeated water in the tank 17 to the UF module 12 through a back water automatic valve 19. And washing water contg. turbid components removed from the inner surface of the hollow yarn membrane is discharged, through a washing water discharge automatic valve 12, to a concentration tank 2, where concentrated sludge 3 is precipitated and supernatant fluid 4 is returned to the sedimentation basin 1.

Title: Auto-tensioner
Inventor: USHIO SADAKATSU
IPC: F16H7/12
Filed: 1988-04-01
Abstract: PURPOSE:To have a damper function and also follow rapidly the sudden slackening of a belt, by making one of the two slide surfaces of a fixed member and a movable eccentricity member, a low friction slide surface, and in addition, interposing the oil of a high viscosity between members. CONSTITUTION:In the case of the increase of the tensile strength of a belt 27, a vertical load between the high friction slide surface 17a of a middle annular member 16 and the surface coming into contact with this, becomes larger, as a movable eccentricity member 19 receives a large radial load from the belt 27 through idlers 22, and the mutual fixation is done due to a large static friction. And a damper effect is displayed on account of the viscous resistance of the oil of a high viscosity between the low friction slide surface 18a of the middle annular member 16 and the surface coming into contact with this. When the vertical load becomes smaller, the static friction also becomes smaller, so sliding is apt to occur, but because of the oil of a high viscosity, sliding is slow.

Filed: 1986-04-08
Abstract: PURPOSE:To obtain a photosensitive body having a filter layer having high wear resistance causing hardly deterioration of electroconductive characteristics easily and with high efficiency by adhering a filter layer in the condition of negative pressure to the upper or rear side of a photographic sensitive body interposing the adhesive layer. CONSTITUTION:A supporting body having a thin film comprises a supporting body 1, an adhesive layer 2, and a transparent thin film 3b. A filter layer is formed on he thin film surface on the supporting body by the process that the thin film is printed directly with a colorant and ink contg. a transparent resin, pref. a thermally or optically hardenable resin, or the filter layer having desired pattern is formed basing on the technique of photoresist. Suitable adhesive for bonding the thin film to the photosensitive body may be a similar one as used for forming an adhesive layer on the supporting body or in the adhesive layer provided to the thin film. By executing bonding of the thin film to the photosensitive body under negative pressure, generation of foams between the surface of the photosensitive body and the thin film can be prevented. Thus, the adhesion is improved and uniform bonding of the surface of the photosensitive body to the thin film can be achieved.

Title: Semiconductor device
Inventor: NARITA HIROSHI
IPC: H05K1/18
Filed: 1990-03-29
Abstract: PURPOSE:To judge whether solderability is perfect, only by observing whether an outer lead is colored or not, by a method wherein the solder-plated surface of an outer lead is coated with material whose hue is different to that of the solder-plating. CONSTITUTION:One end portion 1a of an outer lead 1 which portion is buried in sealing material 2 is connected with the surface electrode of a semiconductor element 3 by using a metal thin wire 4. The other end portion 1b exposed from the sealing material 2 is coated with solder-plating 5. Thereon a thin film 6 is formed by copper-plating or gold-plating, and then lead cutting and bending process are performed, thereby forming a semiconductor device. The outer lead 1 exhibits the hue of red-brown or gold which is quite different to silver-white, the hue of solder. The copper-plated red-brown-colored thin film 6 or the gold-plated gold-colored thin film 6 is heated when a device is mounted on a printed wiring board 8. In the state where the solder plated on the outer lead is fused, the thin film 6 is gradually diffused into the fused solder. In the period required for soldering, however, the thin film 6 is not completely diffused but exhibits the hue of red-brown or gold.
